Ok guys here is the deal...

I know a girl through mutual friends. We started talking and texting often a few weeks ago. We've hungout a few times, but I made the mistake of not escalating things. I feel like she's pulling back, so I stopped texting her for the last week or so. How do I come back and turn things sexual.

If she's pulling back, why did you pull back too? If she's moving towards you, then YOU can pull away, but only slightly otherwise you'll come across as aloof. But again, I'm puzzled as to why you pulled back - perhaps safeguarding against rejection because you felt a lack of interest on her part and were too 'proud' to put yourself out?

Regardless, you need to re-engage her. Call/text her, but ONLY with a plan - get her out again. you can go "hey babe (however you casually address her) I'm gonna be in your neck of the woods saturday, we should go grab a bite to eat"

something along those lines
